I did a search and I believe my best bet to move my shed up 10 inches or so to get it out of flood danger is to jack it put and place it on concrete block footers.

Anyone have suggestions on what size jacks to look for at the home stored. I need to move it up 10 or so inches from where it is. It is already 4-5 inches off of the soil. Do I need to move it a lot to do my work? how many jacks do you think would be needed for an approx 8x8(or 10) shed/barn?

Thanks for the suggestions. I haven't see any detailed instructions anywhere.
